Patent GB-2141838-A (GB)
Title: Stage lighting control system
Inventor: BERTENSHAW DAVID RONALD
IPC: H05B37/02
Filed: 1983-12-02
Abstract: A stage lighting control system has a main executive processor rack unit, a portable desk controller including a local microprocessor and a plurality of output channel slave processors controlling groups of dimmers. The dimmer control contacts in the desk are scanned and changed state data transmitted to the main processor as an asynchronous serially coded signal so that a low capacity link can be used which enables the desk to be located remote from the rack. This data is stored in the executive processor's main and/or preset stores and used for updating the RAMs associated with the slave processors to vary the lighting levels. Lighting level information is recorded using a channel code so that patching enables different arrangements of dimmer circuitry to be controlled in accordance with the original record to give the same lighting effects.

Title: Tool decontamination unit for the removal of radioactive, chemical and biological contaminants
Inventor: FOWLER DAVID E
IPC: G21F9/00
Filed: 1985-09-05
Abstract: Tools, equipment and weapons contaminated with radioactive, toxin, biological and/or chemical contaminants are deposited in a cleaning chamber and are sprayed with a solvent under high pressure. The solvent dislodges particulate contaminants and dissolves chemical agent contaminants and the solvent so sprayed containing both suspended and dissolved contaminants is drained to a distillation means. Within the distillation means there is a neutralizing agent which deactivates the biological and toxin contaminants and chemically oxidizes the chemical contaminants removed from the item being decontaminated in the cleaning chamber. Pure solvent vapor generated in the distillation means is condensed to a solvent tank for reuse in the spraying operation for further decontamination. Drying of the tool, equipment or weapon being decontaminated is accomplished by circulating hot, unsaturated solvent vapor through the cleaning chamber and about the item being decontaminated.

Title: Fiber optic pressure sensor
Inventor: JAEGER RAYMOND E
IPC: G01L11/02
Filed: 1986-01-31
Abstract: An arrangement for an optical fiber pressure sensor is comprised of two coating layers (15,17) concentrically clad to and coaxially oriented with an optical fiber (11,13). The first coating layer (15) is comprises of a relatively hard optically lossy material which absorbs any light radiating outwardly from the optical fiber (11,13). The second coating layer (17) is comprised of a compliant material in which granular particles have been uniformly dispersed. In response to any pressure laterally applied to the sensor, the compliant coating layer (7) imparts micro-bends, onto the optical fiber (11,13), which, in turn, couple light from propagating modes to non-propagating modes. As a result, the amplitude (or power) of the light exiting the optical fiber (11,13) advantageously decreases in response to this pressure. <IMAGE>
